Strange. I've heard that several times about cops, but I know better than to generalize. Apparently the screening for ethics and abusive behavior/anger issues when you join the force isn't terribly accurate. If they're hurting and need more new officers, I suppose like the armed services, they lower their standards. But still, there are always those charming liars who can pass any test.

Sorry you went through all this and now you're worried about the next person he's going after. It probably wouldn't help to send her a note or even make a complaint to his precinct. Was he ever physically abusive or just manipulative? If so, after the complaint, you'd have to get a restraining order, but even then, it could be dangerous. Can you move away per chance?

Is your job impossible to transfer to another city?
